Writing the Maturity Email and Judging AI Output

This chapter covers the individual email assignment, worth 20% of the grade and due on Friday 16 October 2026. The task had three parts with different readers: a report for the lecturer comparing your own DELTA-Plus analysis with the output of two generative AI programs, an email to the chief executive describing the company's maturity in words and giving exactly three urgent recommendations, and a reflection on your judgement and the limits of AI.

The chapter sets out the word ranges, the format and appendix rules, and the six rubric criteria with the points each carries, then shows how to critique an AI claim with case evidence. A worked paragraph for an invented electricity retailer turns factor scores into manager language, and a practice card models one reflection insight.

The same skills, scoring from evidence and explaining a judgement briefly, carry straight into the DELTA-Plus question on the test. Treat it as rehearsal for that question.

Worked example · free

Check a draft against the permitted word range for each part

Q [4 marks]. AskSia-authored practice. A draft has a Part 1 report of 640 words, a Part 2 email of 470 words and a Part 3 reflection of 520 words. The brief allows 350 to 600 words for the report, 500 to 800 for the email and 300 to 600 for the reflection. Which parts need changing, by how much, and what is the allowed total? The marks shown are an AskSia study allocation, not an official University marking scheme.
Word ranges for the three partsThree horizontal bars on a word-count axis from 0 to 800: the Part 1 report spans 350 to 600 words, the Part 2 email 500 to 800 words and the Part 3 reflection 300 to 600 words.0200400600800Part 1 reportPart 2 emailPart 3 reflection
Each bar shows the permitted word range for one part on a common axis from 0 to 800 words; the email is the longest part, while the report and the reflection share the same 600-word ceiling.
  • 1Part 1 report: 640 words is above the 600-word ceiling by 40 words, so cut at least 40 words.
  • 1Part 2 email: 470 words is below the 500-word floor by 30 words, so add at least 30 words of argument for the recommendations.
  • 1Part 3 reflection: 520 words sits inside the 300 to 600 range, so no change is required.
  • 1The allowed total runs from 350 + 500 + 300 = 1,150 words to 600 + 800 + 600 = 2,000 words; the draft's 1,630 words is inside it, but each part must meet its own range.
Cut the report by at least 40 words and lengthen the email by at least 30 words; the reflection already fits. The draft total of 1,630 words lies between the 1,150 and 2,000 word limits, but the ranges apply part by part, so a compliant total does not excuse a part outside its own range.
Sia tip — Move words from the over-long report into the email's reasons for each recommendation, where the rubric rewards argument.

FAQ

Writing the Maturity Email and Judging AI Output FAQ

Could I use ChatGPT for the email assignment?

Yes, within rules. Your own DELTA-Plus analysis had to come first, then two generative AI programs were applied and compared with it. AI could help draft or polish the email, but you remained responsible for checking the recommendations, citing AI in APA 7th style and placing every prompt and output in the appendix.

How many recommendations should the CEO email contain?

Exactly three, no fewer and no more, chosen as the most urgent ways to improve the company's data and analytics maturity. The rubric's full-marks band asks for a nuanced, well-argued email with three recommendations and clearly stated reasons for choosing them, so explain why each one comes before the alternatives.

Where do AI conversations go in the submission?

Only in the appendix. The brief tells you not to put screenshots, copied messages or transcripts in the report itself. The appendix must contain your prompts and the full AI-generated output without changes, and the integrity, referencing and format criterion checks that it is complete.

What should the reflection focus on?

Three key insights from your own experience of this assignment, chosen from prompts such as your most difficult judgement, evidence that changed your view, and the limits of AI on this case. General pros and cons of AI are excluded, and you should not repeat the AI evaluation already given in Part 1.

Why is the email assignment useful for the test?

The course described the assignment as crucial preparation for the test's DELTA-Plus question. Both tasks ask you to score a company's factors from case facts and to justify a recommendation. Practising the independent analysis before consulting AI builds exactly the habit a closed-book, time-limited question demands.

Study strategy

Assessment move

Even though the deadline has passed, reuse the assignment as test practice. Take your submitted DELTA-Plus analysis and rewrite it from memory in 20 minutes as about 150 words: one goal, five scores with evidence, one recommendation. Compare the rewrite with the original and note which scores you could not justify without the case open.

Then reread the feedback against the six rubric criteria and list the two criteria where you lost the most points; for each, write one sentence describing what you would do differently. For manager language, practise converting any score line into three plain sentences: what the firm does well, what holds it back, and what to do first.

Finally, keep a short log of AI prompts you try on practice cases and the errors you caught, because recognising confident but unsupported claims is a skill the course keeps rewarding.
